  • This change from fossil fuels to the endless power of renewable energy will take the same passion, energy and commitment shown by elite athletes who are determined to win.Athletes like FuifuiMoimoi? He’s got that “don’t mess with me” look.Why does Australia need to ditch its coal and gas generators as fast as it can? What’s wrong with coal and gas?
  • This beautiful planet is our home – and 7 billion humans have filled every corner of it. This generation of human life, our generation, is the healthiest, longest lived, richest and most comfortable generation in the 300,000 years since Homo Sapiens evolved. This has been built in the past 150 years on the energy provided by fossil fuels. Coal, oil and gas.For most of those 150 years we didn’t know that coal, oil and gas were damaging the planet. Now we know that when they are burnt they release gases like carbon dioxide into the atmosphere. This is causing the planet to warm up.
  • This graph from the Potsdam Institute shows global temperatures from 1900 and projects forward to 2100. You can see that between 1900 and 2000 temperatures rose a little. [They rose by 0.7C]. The second part of the graph shows expected temperatures over the next 100 years.This pink area shows the predicted rise in temperatures if countries do not take action to reduce their CO2 emissions. This is the Business As Usual scenario. By 2100 global average temperatures will be 4-6 degrees warmer. These are averages for the whole globe including land and water, equator and poles. Temperatures over land will be higher than over water, and there will be local extreme highs that are much higher than anything we know today.Right now, with 0.7C warming, new high temperature records are being broken at an increasing rate. It’s not just one or two days at 42C, it’s a week in a row. Like we saw in NSW in 2011. Most of you will be around in 2040, 2050 and further. These are the conditions you will live in. What will summers be like then if nothing is done?Mainstream science recommends that countries take action to ensure that temperatures do not rise more than 2C. They call this the guardrail.
  • Professor Schellnhuber [Shell-en-hugh-ber] from the Potsdam Institute says – The difference between 2 degrees and 4 degrees is human civilization.This is not contested by mainstream science. We need to let this sink in. Perhaps we need to wrestle with it for a while. We certainly can’t ignore it.Of course we all want to choose the 2° option. We want the Guardrail.
  • We, all of us, the smart guys like Professor Schellnhuber, the strong guys like FuifuiMoimoi and Frank Puletua, are fighting for our children and grandchildren. We’re not negotiating. You don’t negotiate with gravity. We’re in a fight.We need to tackle this with the “Don’t mess with me” attitude of a father protecting his children, a mother protecting hers.And where is the fight?
  • The fight is with our carbon emissions. The more carbon dioxide we put into the atmosphere, the warmer it gets. From today, another 565 gigatons of carbon dioxide will take us to an average global temperature that is 2°C above pre-industrial levels. Think like a scuba diver – we’ve got a ration of 565 gigatons. When it is used up we can’t use any more. We’re already in the danger zone. That’s when scuba divers head for the surface – fast! At current emission levels (31.6 GT in 2011 and rising every year), we will reach the 2 degree guardrail by 2030 and extreme weather events will have quadrupled. Most of you won’t have children in 2030 – this is before your children are born.We need a roadmap for Australia to reduce its carbon emissions quickly.
  • This roadmap shows the route from Glen Innes to Grafton. Right now 92% of Australia’s electricity is generated from coal, gas and oil. We have to stop adding carbon dioxide to the atmosphere and we have very little time to do it. We need a GOOD map.
  • The Stationary Energy Plan by Beyond Zero Emissions and Melbourne University outlines how Australia’s electricity sector can go 100% renewable in just 10 years.Three years ago this seemed far-fetched to many people. But this year the government released its own report that found it is technically possible and economically affordable to make the journey to endless power.What would 100% renewable electricity look like?
  • World solar resources – Australia has outstanding sunlight. Countries further from the equator get less sunlight. And countries around the equator have a lot of cloud. Australia is right in the sweet spot for sunlight.Technically, Australia has enough solar resources to meet the entire energy demand of the whole world for all purposes.
  • We also have excellent wind resources. Hundreds of kilometres of land areas across large areas of the country, as well as a strip of ocean around more than three-quarters of the coastline.  Australia also has extensive geothermal potential. It isn’t included in the plan because the technology to tap it is not at the commercial off-the-shelf stage. Australia has fairly limited hydro resources, and the easiest resources have already been utilised, so new hydro doesn’t feature in the plan.
  • Photovoltaics generate electricity that can be stored in batteries to be used when needed.Solar thermal stores the heat from the sun, and uses the heat to generate electricity when needed.
  • This is the Concentrated Solar Thermal technology that is proposed in the Plan. It is a technology that has been around for a while but recent developments with molten salt storage allow it to dispatch power 24 hours a day. And the technology is at the point where it is being deployed in commercial situations in countries like Spain, the US, Morocco and Tunisia. This picture shows the Gemasolar plant in Spain that began operating in 2011. It produces 110 GWh/year - sufficient to meet the needs of 25,000 homes. You can see that it is a large field of mirrors, 2,800 mirrors, that focus the heat of the sun onto a central tower. It is quite beautiful, isn’t it? Like the pattern of seeds in a sunflower.Solar thermal uses the same principles as regular electricity generators that use steam to turn turbines.
  • The Plan is based on these extra large wind turbines. Made by Enercon, they have a 7.5MW capacity.Right now wind power is the cheapest, most technologically mature, renewable energy source. The Plan outlines 23 wind regions across those windy parts of the country we saw on the wind map. Each wind region would have 330 of these turbines.
  • Our plan is not the only one that gives a roadmap for a continent-wide electricity grid based on renewables. The Desertec plan covers Europe, North Africa and the Middle East.Solar thermal is a big part of this plan, and new plants are being commissioned in Morocco and Tunisia.Saudi Arabia has budgeted $109 billion over next 20 years. UAE also.
  • NREL (National Renewable Energy Laboratory) has just done the same detailed exercise showing how the US (lower 48) electricity could be 80% renewable by 2050.So, our roadmap shows that we can meet Australia’s electricity demand using solar thermal and wind generators along with an enhanced grid.But the question remains how much will it cost? Do we have the capacity to roll out 200 Concentrating Solar Thermal Plants and over 6,000 wind turbines?
  • We started by looking at the need for an energy revolution. The laws of physics describe the role of greenhouse gases in warming the planet. We must act.Then we looked at a roadmap for action. We see that we have the technology, the capacity and it is affordable.Let’s take a quick look how this energy revolution will benefit all Australians, especially your generation.Most important is that we will stay within the 2C guardrail for safe climate. This means that you will enjoy the same climate that all of humankind since Homo Sapiens have enjoyed. This is the climate where all our foods, plants and animals evolved. Almost as important is that the world’s ecosystems will continue to work as they always have. Just one example – the oceans today are more acidic than they have been for 25 million years. Already coral reefs are dying. If oceans continue to get more acidic by absorbing carbon dioxide from the atmosphere, then small shell creatures at the bottom of the food chain won’t form shells and they’ll die out, taking all the creatures above them on the food chain. 1.4 billion people depend on oceans for their protein. Least cost pathway to decarbonise our economy. The later we leave it, the more it will cost.So, where to from here?
  • There are two ways you can help Australia’s energy revolution.On the personal front, you can reduce your coal, oil and gas consumption. Energy efficiency, rooftop solar or solar hot water are good things to do. Small things like green shopping bags as well as big things like home insulation.What you do makes you part of Australia’s energy revolution.As well as making personal changes, we need to advocate for changes in the whole system of electricity generation.
  • Thank you for your time and interest. I encourage you to find your own “Don’t mess with me!” attitude and support this energy revolution as Australia makes the Journey to Endless Power in your lifetime.http://bze.org
